Jhbuild does it by default.  The opposite is to strip the symbols out of
them (which distros do to distribute binaries in order to save disk
space).

how exactly you are debugging the program.

If it happens you stop follow into a library that does not have
debugging symbols, assembly is what you are going to obtain.  Remember,
that jhbuild tries to build what you need, not everything down in the
stack.

That said, I would try something like:

$ jhbuild shell
$ nemiver /path/to/jhbuild/bin/gnome-photos

replace 'nemiver' by the debugger interface of your preference.
